Basic Programming Structures

• Sequence

  Instructions are executed, one at a time, in a predefined sequence.

• Selection

  Also known as "branching". Some instructions are executed depending on the results of a test of a condition. These tests may be "nested"

• Iteration

  Some instructions are performed repetitively a finite number of times. The number of iterations may be defined prior to executing the loop, or during the execution of the loop.
